You are correct. The major memory leak I was having was due to vcache using
all of my RAM. Once used, it was not returned.
I have made the following settings as you suggest:
[vcache]
chunksize=4096
maxfilecache=40960
How do you know these are the ideal settings?
Thanks much, neo

~ Neo,
~ when you used 1 GB of RAM, you were getting system lockups
~ because you didn't
~ set your MAXFILECACHE. The MINFILECACHE setting is not that
~ important. When
~ you set the MAX, Windows will probably just use that amount.
~ With CacheMan (
~ http://www.outertech.com/product.php?product=3 ), I experimented
~ with the CACHE
~ size and couldn't get it to go over about 55 MB's. Don't
~ remember the exact
~ figures, I think I had 192 MB's at the time. Cacheman is
~ totally free with no
~ adware.

~ Utilities v4.0 (
~ http://mcafeestore.beyond.com/Product/0,1057,3-18-ML100110,00.html ). I
~ recommend you place these settings in your SYSTEM.INI file:
~ [vcache]
~ chunksize=2048
~ maxfilecache=40960
~
~ You don't need a VCache larger than 40 MB's. Anything larger
~ will just slow
~ your machine. Your CHUNKSIZE should be equal to or half of your
~ hard drive
~ partition cluster size. If your partitions are all smaller then
~ 8 GB's, you
~ should set your CHUNKSIZE to 4096 or 2048. I should change my
~ CHUNKSIZE to
~ 4096.
~
~ You should allow Windows 98 to manage your swap file. Setting
~ it to a fixed
~ size is acceptable. Every time you start up Windows must create
~ your 512 MB
~ file. I believe when you shut down Windows deletes your Swap
~ file. This is

~ since I've
~ looked at these things so you'll have to verify it. The total
~ amount of memory
~ available to Windows 9x is your physical memory + your swap file
~ size. After
~ you get NSD, you will get a better idea how your system behaves
~ in terms of Swap
~ File size and you will be able to set an optimized fixed size.
